tag_summary = "The 'nginx' program is prone to multiple directory-traversal
vulnerabilities because the software fails to sufficiently sanitize
user-supplied input.

An attacker can exploit these issues using directory-traversal strings
('../') to overwrite arbitrary files outside the root directory.

These issues affect nginx 0.7.61 and 0.7.62; other versions may also
be affected.";
